I totally support your channel. But I hope you are resting yourself. You don't want to put too much strain on your ligaments and tendons at such a young age. They need to recover just like muscles. Seen a lot of player's try to overwork and have short careers due to injuries from overworking at a young age during development.
You’re dipping your shoulder too much, stay on top of the ball and come down at it. It will give it back spin and you hit dingers. You’re too under the ball by dropping you’re shoulder
Nice swing!! One thing I would say is that after you make contact you almost immediate roll over and if you stayed through a little longer I believe you would hit a lot better!
